First check the if there's a debris screen on the got water inlet, as it may be plugged.
Make sure the hot water volume is good. With hot water hose disconnected at the washer, put end of hose in bucket and turn on hot water. You should get 20L (5Gal) a minute minimum.
If water volume is good and screens are not plugged, then likely the hot water inlet valve has seized. Could be both hot/cold valves are integrated so both get changed. Not a bad idea to just do them both if separate hot/cold valve.If you know how to use a volt meter you could check power at the hot valve to make sure its not a control issue or swap the control wires and select a warm temp cycle. If you get cold water then its not a control issue.(dont forget to put wires back)

I have a Siemens WM16S772DN washing machine and encountered the error code "F:67" followed by repeated beeps. (Note: Siemens and Bosch are related companies). I called Siemens and they said the code means "Fatal error" or program error. The service technician was called, and he replaced the electronic board and reprogrammed it.

The Bosch Logixx 8 washers indicate an F37 error when the temperature sensor is defective. Sometimes this can happen if the incoming water line gets too cold. If that is the case, pressing the temperature button twice may help. (You should see a snowflake in the top left corner of the LCD screen.) Otherwise try thawing the water pipes.

If the problem isn't cold/frozen water lines, then the temperature sensor is faulty, the wiring between the sensor and the control board could be damaged or the control board has a problem getting the temperature information. Check the sensor and the wiring first. Often there is a sheet inside the washer (near the control board) with the expected resistance across the sensor and other parts. Unplug the washer before testing.

Please add a comment with the model of the washer for a parts diagram or price list. If your washer is under warranty, contact Bosch about the error.

You can either take the dispenser out , unclip top part of dispenser, then prise out the insert which has the holes fof the water, or if dispenser is in place ,with a small screwdriver, gently prise the fabric conditioner downwards and with an old toothbrush , remove the black mould

My Bosch Classixx 6 Express 1200 washing machine suddenly developed three faults at the same time, with no fault codes. The water pump, fill and spin cycles all stopped at the same time. I found that the one of the pump wires had come loose from the connector plug. This will not only stop the drum from emptying but will prevent the machine from filling and also stops the spin cycle. These are all interconnected and controlled by the water pump, which has to be working and connected. Hope this helps. My 11 year old machine is now working perfectly.

Bosch dishwasher error code e09. Icon E 09indicates issues with the heating element. Most likely, the device has burnt down and needs to be replaced, but it's not so simple. The flow-through heater in thedishwasher differs from the heater in the washing machine.
